Growth dynamics of tree-line and lake-shore Scots pine (Pinus sylvestris L.) in the central Scandinavian Mountains during the Medieval Climate Anomaly and the early Little Ice Age

Trees growing at their altitudinal or latitudinal distribution in Fennoscandia have been widelyused to reconstruct warm season temperatures, and the region hosts some of the world’slongest tree-ring chronologies. These multi-millennial long chronologies have mainly beenbuilt from tree remains found in lakes (subfossil wood from lake-shore trees). We used aunique dataset of Scots pine tree-ring dat

Combined portal vein embolization and preoperative chemotherapy prior to liver resection for colorectal cancer metastases.

Objective: Compare perioperative course and long-term mortality after liver resection for colorectal cancer (CRC) metastases between patients who had preoperative treatment with portal vein embolization (PVE) and chemotherapy or chemotherapy alone. Methods: Among patients undergoing liver resection for CRC metastases following preoperative chemotherapy treatment, 17 patients who had received pre

Duration of colonization with extended-spectrum beta-lactamase-producing Escherichia coli in patients with travellers' diarrhoea.

Background: Resistant Enterobacteriaceae have become a worldwide epidemic during the last decade and are a great threat to health care worldwide. International travel is a major risk factor for becoming colonized with extended-spectrum beta-lactamase (ESBL)-producing bacteria. Data on the persistence of colonization with ESBL-producing bacteria in the faecal flora are limited.Methods: A prospectiv

In situ bending of thoracic stent grafts: Clinical application of a novel technique to improve conformance to the aortic arch.

PURPOSE: A straight thoracic stent graft often complies poorly with the curvature of the aortic arch. We have previously reported an in vitro model of a modified stent graft that can be bent in situ after deployment to improve conformance to the aortic arch. We now report the first clinical experience with this technique in three consecutive patients. METHODS: Between September 2007 and August 200

Arbetslösheten: ett individuellt problem?

Om det lyckas att göra en av de idag viktigaste politiska frågorna, arbetslösheten, till ett individproblem, har makthavarna - de ekonomiska och politiska - också lyckats lyfta bort frågan om det kapitalistiska samhällets legitimitet från dagordningen.

Genetic control of the variable innate immune response to asymptomatic bacteriuria.

The severity of urinary tract infection (UTI) reflects the quality and magnitude of the host response. While strong local and systemic innate immune activation occurs in patients with acute pyelonephritis, the response to asymptomatic bacteriuria (ABU) is low. The immune response repertoire in ABU has not been characterized, due to the inherent problem to distinguish bacterial differences from hos

Pulsations in the umbilical vein during labor are associated with increased risk of operative delivery for fetal distress.

OBJECTIVES: Under physiological conditions the blood flow velocity waveform in the umbilical vein (UV) has an even non-pulsating pattern. Pulsations in the UV have been described in human fetuses exposed to chronic hypoxia and heart failure. Current techniques for fetal surveillance during labor and delivery involve a risk of both over- and underestimation of fetal hypoxia. We aimed to examine whe

Le développement morphosyntaxique du syntagme nominal chez des enfants et des adultes : approche générativiste

Le présent travail veut s’inscrire dans une tradition de linguistique appliquée dont l’ambition consiste à allier théorie et empirisme. Lorsque l’on tâche de combiner deux domaines, on pourrait espérer qu’ils s’avèrent mutuellement enrichis ; Dans le meilleur des cas, la théorie permettrait non seulement l’élaboration d’hypothèses et de questions pertinentes sur les données mises en place par la d
